753 edge blades on logo 700

[nanmadpad]

Will the 753 mains that Mikado sells work on the 700 extreme along with the stock tail blades

[I Fly Helis]

Yes, they will work, but are not recommended. I do not have experience with them, but I would recommend gearing down and running a lower head speed. You will need to change many settings to get it to fly well and not fry your esc. You may also want to increase the tail rotor disk size and use 115mm tail blades, although I would need someone else to confirm whether or not those would be too large to use with the 753mm blades.

If you wanted to convert your heli to use exclusively 753mm, I would suggest changing your motor to the Scorpion HK 5035-380 to allow for more torque and possible add a heat sink to your ESC to be safe.

Good luck!

I have ran the 753's on my 700xx. Very light and floaty but its really too much blade for a 12s setup. Running 716's now.

[guyguerra]

I considered the same idea when I switched my 800 from 753's to 813’s. I had a spare set of 753's and crashed my 700. I can say that after running both blades on the 800 I prefer thee 813's, which are now hard to find. For the 800 the 810mm blades would be my next choice.
The 700 is a different animal. It's smaller than the 800 yet many of the parts are the same. My ESC's and motors are even the same, though the 800 is 14S and 700 is 12S. Yet the weight and size difference is substantial.
I ran a post with the same title you have about 3 months ago and talked with Mikado about it as well. I even found a YouTube vid showing the 753's on a logo 700. I finally decided it was outside the specs for the machine, and went with the largest blades I could find, but stayed below the 750 max size. There's not much in 750mm blades on the market. I think I ended up with about 720mm but am not positive. I can check. Anyway, there is so much power from this size blade (720 range),on a logo 700 that I just put the 753's away as spares for the 800. You just don't need something out of spec to "make a Logo 700 fly better". If you are considering modifying a 700 look into an 800. They don't "fly the same" and are two very different machines imho. The 700 is a much faster, more aggressive and nimble machine. It would be a waste to use 700mm or 710mm blades on the Logo 700 though, the larger blades, as I also found on the 800, make these two models noticeably fly better.

It really depends what kind of flying you want out of it. 753s will work really well to turn the 700 Xxtreme into a floater, great for low headspeed smooth 3D. But if you're wanting to pull a lot of pitch and fast cyclic response, it would be a mistake to go that big. Definitely stick with a good (light) 715 if you want responsiveness and lower disc loading. Otherwise, as already stated, to go that long and put power to it, you'll need a bigger motor and probably will want 14s.

I'm running 753's on 14s 5000. Kosmik 200 and Pyro 800. Head speeds 1800, 1900 and 2000rpm. I will never go back to 713's on this heli but when the lighter plastic Logo 700 comes out I'll give them a try again.

That's intersting and the first "first hand" comment I've heard on this set up. I just received a pair of 813's for my 800 (they are hard to find) so I'll try the 753's on the 700 next week and post how it does. This inspires me, and I've got nothing to lose since the 753's are now spares sitting in the cabinet.

[mahbouni]

Hemp is right though, 12s 5000 will be be stretched to turn 753m blades. It will be fine for light 3D but if you're wanting a power house then you'll need to spend $$$ on a more substantial power system.

[guyguerra]

I somehow missed the part where you said yours is 14S. There in lies the limit for mine, which I knew, and forgot. My 12S isn't gonna "sling" it. Your 700 is almost the same as my 800 other than the boom length.

I ran the same setup, with the pyro 800, and again with the scorp 4530-450.
It certainly doesn't turn it into a floater, it's still slow on collective, and the larger 753mm blades are heavy, they slow the cyclic. Which was the logo700's saving grace, excellent cyclic response.

I think it is very floaty. The hang time is like nothing I've ever flown before.

Once you go to 753mm blades it is no longer a 700 but a 750 size machine, with different flight characteristics. I would expect the agility to decrease further with the Logo 800.

Another thing to consider is that the original Edge blades were never the snappiest blades. If you compare like for like, Edge 693 vs Edge SE 693, there is a quite a difference. I had them on my 600SE and they had a lot less collective pop than other alternatives.

I'm running Rotortech 760mm now, which seem a bit quicker than Edge but they still don't have the snap of SAB, Edge SE or Align. Rotortechs fly very precise and the stops are crisp with no bounce. That's perfect for my flying style. My buddy has a tri blade Goblin 700C. Very agile but it won't help me take my flying where I want it to be.

Depends what you've got to compare it to. It's still heavier disk loading than a 690sx. And much, much heavier disk loading than my e820 on 780mm blades, even though it's running a 5035-380 and 14s. That e820 is more agile than the l700 was on 753mm blades, and the difference in collective "whomp" is like comparing a sports car to a moving van. So certainly not necessarily a size thing alone dictating cyclic or collective performance.
The edge 753mm are very heavy though, they weigh as much as most 800mm range blades, and the chord wise balance is very conservative. Possibly explaining my extreme disappointment in my 14s 4530-450 powered logo 700 on 753mm blades. On paper it looked like a killer setup, in reality, it was precise, but boring to fly, and short flight times due to the excessive mass in the drivetrain and blades.

A little OT I'f I may.

Nathan ...

I built up a logo 770 this past winter.

logo 700 frame with logo 800 tail section trimmed 50mm ( 100mm difference between booms - figured 780mm is in the middle of 753 and 813 )

logo 800 esc and motor
silverline vbar / VBC
8917 / bls 256
bank 3 running 2000 rpm on 11.5 (or maybe 12) degree pitch.

What would you suggest for blades ?

I got a set of sab 780 blackline 3ds blades on it now.
I also have a white set of sab 780's ( came with g770 v1 )

I don't have any experience with the align 780's ( I assume align for 780 as choices are slim in this range )

Heli feels a bit slow on the cyclic. I was expecting something in the middle of the logo 700-800 range but it feels like it's a step above the 800 in response.

Any thoughts ?

- maybe 2100 ?

Hi Martin,
That head speed question is interesting. The whole project is! I'm sure you know all this, so I'm just wondering things. The max head speed on the 800 is 1800, and the 700 is 2100. I started my 800 with 753 blades then got jaded with 813's. I recently wanted to try the 753's again, and now that I know how it flies with both, I put the 813's away. So running 753's on a larger frame (boom) at 1800, even 1720 on I1 and getting good, very fast precise movements. Your running 2000 which sounds like a lot, yet the cyclic response is slow. Could it be your Vbar settings? Even the 700 at 2000 is snappy. Silly question, but I'll throw it out in case. The specs for this servo are based on 7.4v, if you happen to be using a 6v bec you will see a cyclic speed slow down. I couldn't tell from the post so I apologize if this is a stupid question.
What happens if you put 753's back on it?
Just thinking.

It's a bit interesting of a scenario. Not seeing why it a bit slow.
I used the same settings as my 700 does, also similar #'s to the 800.

I run my 800 at 1850 for 3d and 700 at 2100 I recall.

RX pack is a 2s2p 4000 lipo , VBC says about 8 volts for most flights

I don't have a set of 753 blades , I've read there a heavy slower blade. Do wish I had a set to try but with more than 1 person commenting on a heavy blade it's not worth $174 to try out.
So I bought the sab 770 blades ,new blackline units. Mabye there a heavy 770 blade ? What I should do is take the white 770 blades off my goblin 770 v1. That setup had a quick response.

I do need to spend more time on it though , only have a few flights so far and I shouldn't pass any judgement till a good 20 flights in reality.

I was hoping NTM had tried the 770 sab's and align 780's and had some comparison thoughts on the differences

Better late than never ?

The align 780's are the better blade, they're faster on cyclic, and track better. The sab 770's are a bit flexy.
On a side note, it's a pity that thunder tiger tanked out, my e820 is an absolute beast on those 780mm blades. It tears the pants right off of both my 14s logo xx, and 14s sab 770.
Hopefully the new Mikado 700 doesn't let me down (again).

[rcmarty]

Thanks Nathan

Good to know how the blades play out.

I got about 10 flights on the 770 so far to feel it out.

Still had that mellow flight feeling to it.

Then I decided , lets see what it will do.

Opened up the bag of tricks and let it rip.

Turns out once you start to lean on it , it perks right up.

My 800 is similar to that but with a smaller margin , I think I've got the hot side tuned up high so the transition gap is narrower to the hot setup.

I'm happy with it now , just need to get aggressive to wake it up.

Might tune up the 770 or detune the 800 , not sure. I like the slowness for the precision stuff and still can wanabee smack it if I wan't

Poor ec5 couldn't take it the other day . Unsoldered the jumper and did a 25' auto.
Broke the landing gear and the bottom side of a mint canopy
No need to carry around in a box no more I guess.


I hope to get out to alberta one day to do some flying with yourself and shawn one day. Hopefully next year i'll get in on the ercha. The time I went . calagary flooded and drove the attendance down.

I don't know if this applies but I have Logo 700 xxtreme, Logo 800 xxtreme, Trex 700L Dominator and Trex 800 Pro which has the 780 Align Blades.
The 800 Pro absolutely shocked me with collective response by comparison to the others and the cyclic response is impressive also.

Yes, my final form after many, many helis is a 14s raptor e820 on the 780mm align blades.
Best performance and flight time compared to any other heli I've tried or owned. The mikado products aren't even in the running currently, hopefully they can be on top again when the new 700 comes out.

[Stallion]

I have upped my Logo 700 Xxtreme to a 14s Setup but i am still on 710mm rotortech blades and of curse the disk load is to heavy. I do like the rotortech blades but the next size is 760mm.

My question is: will it fit on the stock 700 xxtreme?? What blade size can he handle.

P.S.: like rail blades too but they are even 766mm

Thanks for any insights guys
